BROOM-MAKING MACHINE.

Specification of Letters Patent.

Patented Apr. 18, 1911.

Serial No. 612,926.

To all whom 'it may concern:

Be it known that we, HARRY E. SMITH and NORMAN H. BEEBE, citizens of theUnited States, residing at Wichita, in the county of Sedgwick and Stateof Kansas, have invented certain new and useful Improvements inBroom-Making Machines, of which the following is a specification.

Our invention relates to an improvement in broom machines, and theobject is to provide means whereby the clamping members will be causedto be pressed against the corn or fibers and fastened together. Theinvention consists in certain novel features of construction andcombinations of parts which will be hereinafter fully described andpointed out in the claims.

In the accompanying drawings :Figure 1 is a view in side elevation; Fig.2 is a front end view; Fig. 3 is a rear end View; Fig. 4 is aperspective view of the principal moving parts, showing them detached;Fig. 5 is a perspective view of the staple hopper, showing one of thetubes connected thereto and with one end removed; Fig. 6 is a detailview of the chute; Fig. 7 is a detail sectional view showing the mannerof driving the staples through the clamping members and corn, anddisclosing the manner of cutting off the end of the corn at the upperportion of the clamps; Fig. 8 is a detail view of one of the stationaryplunger-s, showing the manner of clenching the staples; F ig. 9 is alongitudinal sectional view of the main operating shaft; Fig. 10 is aperspective view of the bracket upon which the broom handle issupported; Fig. 11 is a view in elevation of one of the clampingmembers; Fig. 12 is a plan view showing the two clamping membersconnected together; Fig. 13 is a view in side elevation of the completedbroom; and Fig. 14 is a detail view of the broom handle.

A represents the body of the machine, which is provided with an enlargedmouth or slot 1, in which the broom is formed. Mounted upon the body isa shaft 2, which is provided with an opening 3 which runs longitudinallythereof. A rod 4 is mounted in the opening 3, and is connected to theshaft by a pin 5 which passes through slots 6 formed in the shaft. Thepin passes into a collar 7 which is slidably mounted upon the shaft, acoil spring 8 bearing against the collar and one of the standards 9, fornormally holding the rod at the inner end of the opening 3.

Loosely mounted upon the shaft 2 is a gear wheel 10. A clutch 11 iscarried by the rod 4, and the clutch is keyed to the shaft 2 by key 12.The connection between the clutch 11. and the shaft 2 by the key 12allows the clutch to rotate with the shaft, and yet have a slidingengagement therewith, whereby the clutch can be thrown into and out ofengagement with gear wheel 10. When the clutch is in engagement with thegear wheel 10, the wheel will rotate with the shaft. The stationaryshaft 13 is mounted upon the body A, and mounted upon the shaft is apulley 14, which is driven by any suitable source of power. Connected tothe pulley wheel is a pinion 15 which meshes with the gear wheel 10, andformed upon the pinion 15 is a pulley 16. A cam 17 is pivotally mountedupon the shaft 2 by means of a bolt 18. A tripping rod 19 is adapted toengage or be engaged by the cam, and pivotally connected to the rod is afoot lever 21, which is pivotally connected to the body of the machine.

Assuming that the clutch 11 is in engagement with the gear wheel 10,thereby causing the shaft and gear wheel to be rotated as the shaftrotates, the cam 17 will come in contact with the tripping rod 19, whichwill cause the cam to be thrown against the 001-.

lar 7, forcing the rod 4 longitudinally, whereby the clutch will bethrown out of engagement with the wheel 10, and the shaft caused toremain idle.

When it is desired to start the shaft, the foot lever 21 will beoperated, drawing the rod 19 out of engagement with the cam, which willallow the rod 14 to move inwardly, whereby the clutch will be throwninto engagement with the gear wheel 10, the spring 8 forcing the collar7 to be moved upon the shaft, thereby drawing the rod 4 into the shaft2.

A vertically adjustable bracket 22 is mounted upon the body at the lowerside of the mouth 1 by bolts 23. The upper surface is provided with aconcave portion 24, in which is received a convex portion of the clampC, Fig. 11. Openings or passages 25 are formed along the outer face ofthe projecting flange 26 of the bracket, these openings passing entirelythrough the flange for the passage of the staples which connect theclamps together. Guides 27 on the body form a guide-way for the lowermovable head 28. The head is caused to be moved upward by a crank shaft30, which is provided with an arm 31, which engages a roller 32 on thehead 28. A cam 33 on the shaft 2 engages a roller 34, carried by thearms 35, which are pivotally mounted upon the body, and which arms arecon nected by a link 36, to which is connected a rod 29 which isconnected to the crank arm 27 of the crank shaft 30. As the shaft 2 isbeing rotated, the cam 33 will be rotated, and engages the roller 34,which will cause the arms 35 to be raised, drawing the rod 29 upward,and causing the crank shaft 30 to be rocked, whereby the lower head 28will be moved upward, and the fingers 37, which are pivotally mounted onthe bracket 22, will be moved vertically by the posts 38 on the head 28.These fingers 37 hold the corn or fibers between the two clamps C,'sothat as they are pressed together,.the fiber will be prevented frombeing forced outward.

Pawls or dogs 39 are pivotally mounted upon the bracket 22. These dogsare adapted to be engaged by adjustable pins 40 which are. mounted uponthe head 28. As the pins engage the dogs, forcing them inward, they willengage the lips 41 on the lower clamp C, which is resting upon thebracket 22, causing the lips to be moved vertically for confining thefibers or corn between the clamps along the outer edges of the clamps.

Slidably mounted in guide-ways 42 is the upper movable head 43, which isprovided with Vertical passages or openings 44, in which plungers 45 areadapted to reciprocate, the plungers being carried by a bracket 46, towhich is connected a roller 47. The lower portion of the head isconcave, as at 48, for the reception of the convex portion of the clampC upon which the head will. be received in pressing the clamps togetherfor securing the corn between the clamps. The upper face of the bracket22, and the lower face of the movable head 43, are corrugated to conformto the corrugated surface of the clamps C, as indicated in Fig. 7, theface of the upper form being a permanent magnet which will retain one ofthe clamps in position, holding it for and during the pressingoperation.

Mounted upon the head 43 is a hopper 49 which one staple is capable ofbeing received and supported. The upper ends of the chutes 50 are split,permitting the disks to pass between the split portions, whereby thestaples will be delivered to the chute directly from the disks. Fingers59, mounted on a bar 60, are received on each side of the.

disks 58, to prevent the staples being carried over the wheel more thanone at a time that is, preventing more than one staple being received ina single notch and carried over and delivered to the chute 50.

A cam 61 is mounted on the shaft 2, and is adapted to engage the roller62 mounted on the movable head 53, for forcing the head downward uponthe operation of the shaft toward the upwardly moving head 28. The head43 will move down upon the bracket 22, compressing the corn or fiberbetween the clamps which are carried by the bracket and movable head 43.During this operation, the cam 63 on the shaft 2 is engaging the roller47 of the plungers 45, causing them to be moved clownward through thepassages 44, and after the corn has become sufiiciently compressed, theplungers will each engage a pin which has been delivered through theopenings 51 and force them through the openings in the clamps, andthrough the openings 25 in the flange 26 of the bracket 22. Thecontinued upward movement of the lower head 28 will cause the stationaryplungers 65, carried-by the head, to engage the ends of the staples 66,causing them to be clenched upon one of the clamps C, as is clearlyindicated in Figs.

7 and 8. The cutters 67, on the head 28, will cut off the ends of thefiber or corn which project beyond the upper curved surfaces of theclamps. These cutters 67 are capable of vertical adjustment upon themovable head, whereby brooms of different thicknesses can be properlytrimmed.

A bracket 68, which is connected to the frame, carries a forked post 69,and a movable forked post 70, the lower end of the post 70 beingconnected by a nut 74 for limiting its upward movement through thebracket, a coil spring 72 engaging the post for normally forcing itupward. A bar 73 connects the two posts together. The nut 74 regulatesthe height of the post 70. The

for the reception of the staples. Chutes 50 broom handle 75 is supportedby the posts,

and the adjustable stop 76 which is mounted upon the bracket, insuresthe holding of the handle in the proper position whereby the corn fiberscan be clamped properly around it, and the handle securely fastenedbetween the clamps.

Counterweights 78 and 79 are connected to the movable heads 43 and 28,respectively, for returning them to their normal positions.

The operation of the parts has been set forth, but to briefly summarize,the shaft 2 is caused to be rotated upon the release of the cam 17,which allows the clutch 11 to engage the gear wheel 10, power beingtransmitted to the wheel through the pinion 15, which derives its powerfrom the pulley 14. Continned rotation of the shaft 2 causes the cams33, 61 and 45 to be rotated, the cam 33 cansing the crank shaft 30 to beoperated,whereby the lower head 28 is moved vertically, and the cam 61engaging the movable head 43 for moving it downward, the clamps C havingbeen placed in position, one held by the bracket 22 and the other by themovable head 43, the handle and corn having been placed in position, theclamps will be brought together, compressing the corn there-between. Theplungers 45, which are suspended from the shaft 2 by the coil spring 77,are caused to be lowered in the head 43 by the engagement of the cam 45.The plungers engage and force the staples, which are delivered to thepassages 44 in the head 43 through which the plungcrs travel, causingthem to be forced through the clamps, whereby the staples are clenchedby the plunger-s carried by the upwardly moving head 28, and the knives67 on the movable head 28 move to cut the projecting fibers along thecurved upper portion of the clamps. By this time, the shaft will havemade a complete revolution, and the cam 17 will be engaged by thetripping rod 19, causing the cam to engage the collar 5 on the shaft 2for forcing the rod 4 longitudinally of the shaft, whereby the clutch isreleased or disengaged from the wheel 10, causing the shaft to remainidle and the gear wheel to continue to revolve. The plungers 45 willmove upwardly with the head 43, but the passages 51 will be closed, andthe staples cannot be discharged in the passages 44 until the head movesdownward, the head 43 moving prior to the movement of the plungers, orsufficiently in advance to allow the admittance of the staples to thepassages 44, whereby they will be engaged upon the downward movement ofthe plungers for forcing them through the clamping members.

The first action is in the raising of the head 28, which causes thefingers 37 to be raised, then the head 43 is moved downwardly,compressing the fiber between the clamps, and as the head 43 ceases itsdownward motion, the cam (33 forces the plungers 45 downward, drivingthe staples through the clamps and corn.

lVhen it is desired to cause the machine to operate again for the nextbroom, the tripping rod 19 is operated by means of the foot lever 21 forreleasing the cam 17 from engagement with the collar, whereby the clutch11 will be thrown into engagement with the wheel 10 and the shaft causedto rotate.
